Acute febrile neutrophilic dermatosis
- also known as Sweet syndrome - is a skin condition marked by fever, inflammation of the joints (arthritis), and painful skin lesions that appear mainly on the face, neck, back and arms. Although middle-aged women are most likely to develop this condition, it may also affect men, older adults and even infants. The exact cause of acute febrile neutrophilic dermatosis often isn't known. In some people, it's triggered by an infection, illness or certain medications. This condition can also occur with some types of cancer and other serious health problems. Most often, it isn't serious and will clear on its own in a few months. Healing is much more rapid, however, with treatment. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
